Abstract (en)
[origin: GB2505489A] The invention provides a communications device for use in a mobile communications system which provides a wideband downlink first carrier, the first carrier providing resource elements across a first frequency range for communicating data. A plurality of resource elements are provided within a second narrowband frequency range 501 which is within the first frequency range. Each sub-frame includes a first wideband control channel 300 in a part of each sub-frame having a bandwidth corresponding substantially to the first frequency range, and a second narrow band control channel 502 in a second part of each sub-frame and having a bandwidth which is less than the first wideband control channel and a duration of the second narrow band control channel within the sub-frame is greater than a duration of the first wideband control channel within the sub-frame. The second narrow band control channel is configured for communicating control information to both wideband mobile communications devices and narrowband mobile communications devices and forms part of the plurality of the communications resource elements of the second frequency range of the second carrier. By arranging for the narrow band control channel to be within the virtual carrier and to communicate control information to both first full capability communications devices and second reduced capability communications devices, the second reduced capability devices can access the narrow band control channel which is shared with the first full-capability mobile devices. This arrangement makes more use of the communications resources available to the communications system.
